Installation options
3.3.1
Process conditions for installation options
The basic TRANSIC111LP version provides the following installation options:
1
In-situ measurement (flange installation)
2
Extractive measurement (installation with sample gas cell)
Information on process conditions for the various installation options can be found in the
Technical Data Section,
“Ambient conditions”, page 101
.
3.3.2
TRANSIC111LP installation for in-situ measurement (with flange)
Filter recommendation
●
Stainless steel mesh filter: Minimum protection against coarse dirt
●
PTFE filter: Reduces the effects on oxygen measurements resulting from water, dust,
other contamination and extremely strong ambient light. Gases and vapors are not
filtered.

Suitable process flanges
Information on the diameter of the TRANSIC111LP flange adapter and flanges can be
found in the Data Table,
see “Dimensions and mechanics”, page 102
.
The smallest DIN flange suited for the flange adapter of TRANSIC111LP is a DIN/ISO 1092
DN50 flange (fitted with M16 hex bolts). The flange adapter is fitted at the factory and is
fastened to the bottom of the adapter with a screw.
NOTICE:
Installation of the TRANSIC111LP special version for ambient gas
measurement is described in
“TRANSIC111LP installation – ambient gas mea-
.
NOTICE: Filters influence the response time
●
For short response times: Remove the filter.
The optical components are then more susceptible to contamination and must there-
fore be cleaned more often,
see “Cleaning the optical components”, page 85
Do not remove the filter when humidity or dirt can reach the optical components.
Read
“Strong light sources near the oxygen measuring probe”, page 17
before
taking the filter out.
●
Do not use a PTFE filter for measurements near the dew point.
●
Short reaction times not required: SICK recommends using PTFE filters and stainless
steel mesh filters.
